Answer Details

The best word to complete the sentence is "happiest". The sentence is talking about a very special day in someone's life, specifically the day they won a visa lottery. When something is the happiest day of someone's life, it means that it is the day they felt the most joy and excitement they have ever felt. The word "happiest" expresses this idea better than the other options. "Happy" and "very happy" are not strong enough to convey the intense emotions that winning a visa lottery can bring, while "happier" suggests that there have been other happy days, but this day is not just happy, it is the happiest.
